Description

Technical Field

[0001] This utility model relates to the field of spinneret processing technology, and in particular to a grinding needle for punching holes in spinnerets. Background Technology

[0002] A spinneret, also known as a spinning cap, is used to transform viscous polymer melts or solutions into fine streams with specific cross-sectional shapes through micropores. These streams are then solidified by a solidification medium such as air or a solidification bath to form filaments.

[0003] During the production and processing of spinnerets, punching operations are required. Generally, there are many through holes on the spinneret, with varying diameters. For through holes with larger diameters, grinding needles are often used for grinding and polishing, while for through holes with smaller diameters, fluid abrasives are often used for grinding and polishing.

[0004] The existing Chinese invention patent document with announcement number CN117943916B discloses a grinding device and method for easily positioned heat and moisture comfort functional fiber spinneret holes. By rotating the main rotating disk, the spinnerets on each limiting component can be rotated to the bottom of the grinding drill bit for hole grinding, improving grinding efficiency. At the same time, the drive motor can drive the rotating shaft and support disk to rotate, so that the processing holes in other positions on the support disk can be rotated to the bottom of the grinding drill bit for positional alignment, reducing the time and procedures of manual operation.

[0005] Although the aforementioned convenient positioning heat and humidity comfort functional fiber spinneret hole grinding equipment and method can solve the corresponding technical problems, the grinding drill bit and the motor connected to the grinding drill bit are usually assembled with multiple bolts. When the grinding drill bit is worn, the operator needs to use tools to unscrew the bolts to disassemble and replace the grinding drill bit, which is time-consuming and reduces the efficiency of disassembling and assembling the grinding drill bit.

[0006] Therefore, a grinding needle for punching holes in spinnerets is proposed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a grinding needle for punching spinnerets, comprising: a grinding needle body 100, a connector 200, and a connecting seat 300 for quick connection. The connector 200 is located at the top of the grinding needle body 100, and the connecting seat 300 is located between the connector 200 and the grinding motor. The grinding needle body 100 and the connector 200 are integrally formed. The connecting seat 300 includes a support 310 sleeved on the surface of the connector 200. The upper part of the surface of the support 310 has a plurality of mounting holes 311 distributed in an annular pattern. By using screws in cooperation with the mounting holes 311, the connecting seat 300 can be fixed on the punch press. The surface of the support 310 is provided with a rotating member 320 and a plug-in member 330 arranged vertically. The plug-in member 330 cooperates with the connector 200 to realize the fixing operation of the grinding needle body 100, and the rotating member 320 cooperates with the support 310 to realize the moving operation of the plug-in member 330.

[0027] The grinding needle body 100 includes an upper needle handle 110. The bottom of the upper needle handle 110 is fixedly connected to a lower needle handle 120 and a grinding needle head 130 from top to bottom. The diameter of the upper needle handle 110 is larger than the diameter of the lower needle handle 120. The grinding needle head 130 has a conical structure, and the top diameter of the grinding needle head 130 is smaller than the bottom diameter of the lower needle handle 120. The lengths of the upper needle handle 110, the grinding needle head 130, and the lower needle handle 120 increase sequentially. Different diameters and different lengths are used, and the grinding needle head 130 is set in a conical structure to better enter the spinneret punch.

[0028] The connector 200 includes a pin 210 fixedly connected to the top of the upper needle handle 110. The pin 210 is inserted into the inner cavity of the support 310. The lower part of the surface of the pin 210 has four positioning holes 220 that are equidistantly distributed in an annular pattern.

[0029] The upper part of the surface of the insert 210 is integrally formed with a protrusion 211, and the inner cavity of the support 310 is provided with a groove 312 that matches the protrusion 211. The surface of the protrusion 211 is slidably connected to the inner wall of the groove 312. Through the cooperation of the protrusion 211 and the groove 312, the insert 210 can be initially limited so that the positioning hole 220 and the connector 330 can be aligned.

[0030] The rotating component 320 includes a threaded sleeve 321 that is threaded onto the surface of the support 310. The bottom of the threaded sleeve 321 is rotatably connected to a ring 322 via a bearing. The bottom of the ring 322 is fixedly connected to four wedge-shaped blocks 323 that are distributed in a ring at equal intervals. The wedge-shaped blocks 323 are arranged in a one-to-one correspondence with the positioning holes 220. A connector 330 is provided between each wedge-shaped block 323 and the positioning hole 220. By rotating the threaded sleeve 321, the ring 322 and the wedge-shaped blocks 323 can be driven to move vertically upward or downward under the action of the thread.

[0031] The connector 330 includes a pin 331 movably mounted on the wedge block 323. One end of the pin 331 extends through the inner cavity of the support 310 and into the inner cavity of the corresponding positioning hole 220. A wedge groove 332 is provided on the top of the pin 331. The wedge groove 332 is slidably connected to the corresponding wedge block 323. When the wedge block 323 moves vertically, the inclined surface of the wedge groove 332 can be used to change the force direction of the pin 331, so that the pin 331 can move horizontally to achieve the locking and unlocking operation of the connector 200.

[0032] The bottom of the inner cavity of the wedge groove 332 is provided with a dovetail groove 3311. The inner cavity of the dovetail groove 3311 is slidably connected with a dovetail tenon 3231. The top of the dovetail tenon 3231 is fixedly connected to the corresponding wedge block 323. When the wedge block 323 moves, it can drive the dovetail tenon 3231 to slide in the inner cavity of the dovetail groove 3311. This can both limit the pin 331, allowing the pin 331 to move horizontally stably, and also play a linkage role with the pin 331, effectively preventing the pin 331 from slipping off the wedge block 323.

[0033] The working principle of this utility model is as follows: The support 310 is fixed to the output shaft of the grinding motor by bolts. When the grinding motor is started, the connecting seat 300, the connecting head 200, and the grinding needle body 100 are rotated, thereby enabling the grinding needle head 130 to grind and polish the spinneret holes. When the grinding needle body 100 needs to be disassembled and replaced, the threaded sleeve 321 is rotated. Under the action of the thread, the threaded sleeve 321 moves vertically downward on the surface of the support 310. The threaded sleeve 321 drives the ring 322 and the wedge block 323 to move downward synchronously through the bearing. The wedge block 323 slides in the inner cavity of the corresponding wedge groove 332. The wedge block 323 drives the dovetail tenon 3231 at its bottom to slide in the inner cavity of the corresponding dovetail groove 3311, utilizing... The inclined structure between the wedge groove 332 and the wedge block 323 changes the force direction of the pin 331, causing the pin 331 to move horizontally under force until the end of the pin 331 moves away from the inner cavity of the support 310, thereby causing the pin 331 to disengage from the inner cavity of the positioning hole 220, thus unlocking the grinding needle body 100. At this time, the grinding needle body 100 is moved downward, causing the grinding needle body 100 to drive the pin 210, the positioning hole 220 and the protrusion 211 to move downward synchronously. The protrusion 211 slides in the inner cavity of the groove 312 until the pin 210 disengages from the inner cavity of the support 310, thereby completing the quick disassembly of the grinding needle body 100. Conversely, the above steps are reversed to complete the quick installation of the grinding needle body 100.

[0034] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
